It looks like this is the cause of the failures:
https://chromium.googlesource.com/chromium/src/+/cfb28f09eed335dec12046d9fb5ebe686d6dfd7c

Some tests were no longer being skipped because the Linux CQ bots were upgraded from Precise to Trusty. Because the Linux RandomOrder builder is still on Precise, it started failing on those tests.

Creating a CL to temporarily skip those tests and creating another bug to upgrade the RandomOrder Linux builder from Precise to Trusty.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/3bb2e052adf2adbb5ebbe4978c285d27e8e43ecc

In RandomOrderExpectations, skip tests that fail on Precise

These tests were originally skipped because they fail on Precise. When the CQ was upgraded from Precise to Trusty, these tests were unskipped. The RandomOrder Linux builder is still Precise, so we need to skip these until we upgrade it to Trusty.
